.PREV DISCUSSION... /Issued 314 PM CDT WED JUL 20 2016/

DISCUSSION...
Strong upper level ridge of high pressure will remain in control
through the rest of the week, with hot and humid conditions
persisting. Heat Index values of 105-108 common in much of the
area again this afternoon, and net result of expected trends in
temp and dew point for Thursday yield similar readings. Will
extend heat advisory for another day but hold off on further
extension at this time, as most guidance continues to support a
more appreciable decline in dew points by Friday. Unfortunately
this will likely result in many areas seeing triple digit temps
for the first time this summer. Isolated convection again has
developed in terrain areas of southeast OK and northwest AR, but
less coverage than yesterday and should see even more limited
coverage next couple of afternoons.

Some minor relief from the heat appears likely next week with some
weakness in upper ridge evident. This should also aid in a bit
more widespread showers and thunderstorms during the early part
of the week.
